Fics like Ace of Spades

Ace of Spades, the most feared name across the ocean, he was the most feared and notorious assassin and informant there ever was. No one knew who or what he was, some say he is the spawn of the devil. And now, the Whitebeards needed his help. And maybe they even get a new son in the process. (Up to chap 52 'The Plight' is main story, the rest are just loose ends and ideas)
